Energy can only be converted from one form to another
eg kinetic energy is converted to heat energy
I would say D. all of the above
<span>both the speed of the wave and the wavelength
- The frequency does not change, but the speed does. If that is true, then the wavelength must also change.</span>
Inside the bar magnet, the magnetic field points from north to south. Statement A is correct.
Magnetic Field:
It is defined as a vector field or the influence of the magnet on the electric current, charges and ferromagnetic substance.
The strength of magnetic field is depends up on the numbers of magnetic field lines per unit area.
- Magnetic field lines emerge from the North pole and end in the South pole of a bar magnet.
- Inside the magnet are also present inside the bar magnet and never intersect at any point.
Therefore, inside the bar magnet, the magnetic field points from north to south.
